The Global Climate Action Summit is challenging people, communities, societies and economies around the world to ‘step up’ and take ambition to the next level across five key issue areas: Healthy Energy Systems, Inclusive Economic Growth, Sustainable Communities, Land and Ocean Stewardship and Transformative Climate Investments. The 2018 Global Climate Action Summit, hosted in San Francisco, USA between 10–14 September, will bring together state and local governments, business and citizens from around the world to showcase climate action taking place, thereby demonstrating how the tide has turned in the race against climate change and inspiring deeper national commitments in support of the Paris Agreement.
